In a follow up post to how-much-space-does-an-air-gap-installation-of-tanzu-tkg-1-6-0-need I thought it would be useful to expand on the initial summary to include an upgrade to TKG 2.1.1.
In the previous 1.6.0 example there was a total of 157 images (881 artifacts) requiring 9.7GB of storage space. However the download process has been modified and doesn’t use a shell script to download files for an air gap registry anymore, but rather a command such as:
tanzu isolated-cluster download-bundle --source-repo projects.registry.vmware.com/tkg --tkg-version v2.1.1This results in 244 tar files being downloaded for a single version of TKG and 45GB of space needed.
When these tar files are uploaded I experienced several problems caused by a redis bug when using Harbor 1.10.x, and the upload command only succeeded once I had upgraded to Harbor 2.5.0.
tanzu isolated-cluster upload-bundle --source-directory ./ --destination-repo registry.sbcpureconsult.internal/tkg --ca-certificate /tmp/ca.crt
In total (for the combination of both TKG 1.6.0 and 2.1.1 releases) there are a total of 177 repositories requiring 20.58GB of storage space.
If I subtract the two figures from one another it indicates that TKG 2.1.1 requires 10.88GB in total.
